I was interested by their mention of "A 2021 systematic review of 102 randomised controlled trials"[0] so I looked it up. The effect size was 4x bigger in mid/low income countries. So, while a valuable result, it might not generalize to the the probable readers of this comment, who are likely in high income countries (and the high income parts of those countries). The more compelling argument IMHO is that few studies capture the nuance of parenting style and outcome, having to rely on aggregate factors like education level and income. I'm willing to be convinced that my specific parenting choices won't impact my kid's adult income, but I'm pretty sure it will impact concrete things like politeness, and potentially even downstream things like overall relationship satisfaction.
